Equivalent circuit models (ECMs) are a widely used modeling approach for lithium-ion batteries in engineering applications. The RC elements, which display the dynamic loss processes of the cell, are usually parameterized by fitting the ECM to experim

As storage technology in electric vehicles, lithium-ion cells are subject to a continuous aging process during their service life that, in the worst case, can lead to a premature system failure. Battery manufacturers thus have an interest in the agin

Single lithium-ion cells within electric vehicles’ battery packs generally show variations in capacity and impedance due to the manufacturing process as well as operational conditions. Therefore, cells connected in parallel experience different dyn

Despite fast technological advances, world-wide adaption of battery electric vehicles (BEVs) is still hampered—mainly by limited driving ranges and high charging times. Reducing the charging time down to 15 min, which is close to the refueling time

Parameter variations of lithium-ion batteries are an important concern because they can reduce the performance of a battery pack. To quantify inherent variations due to production tolerances, battery parameters of a batch of individual cells are expe

The key to the safe and reliable operation of an electric vehicle is the precise knowledge of the state-of-charge (SOC)of its energy storage system. Since this state variable is not directly observable, it is derived from other quantities using model
